ments in Traverse Mechanism, of whichthc following is a specification.

My invention relates to apparatus for spinning artificial silk, and particularly to the traverse mechanism for the spinning boxes. The object of my invention is to provide a mechanism which operates wlthout vibration or undue stresses,by reason of the improved arrangement of theparts to secure a balanced load. A second ob]ect of my invention is to associate with the mechanism a suitable arrangement for bringing the spinning boxes to position for discharge.

In the accompanying drawings- Fig. 1 is a longitudmal section through portion of an'artificial silk spinning frame, to which my invention has been applled ln one form; I

Fig. 2- is a broken section on the line 2-2, Fig.1, of a driving gear for' the traverse bar;

Fig. 3 is a side elevation, partially 1n section, of a modified form of the llftmg cam for the traverse bar;

Fig. 4; is a vertical section through the traverse motion showing the lifting cyllnder which raises the spinningboxes for discharge thereof; and

1917, the filaments of artificial silk, comlngfrom the setting bath over suitable guides or godets, are coiled in spinning boxes rotated at high speed and simultaneously reciprocated vertically to effect the twisting of the filament into a thread, and the coiling of the ,same into a fiber cake. In the arrangement described in the patent referred to, the s inning boxes are carried on bars exten mg longitudinally on opposite sides of the main frame, and supported by rocker arms keyed to a longitudinal shaft, which is oscillated to impart the desired traverse motion to the boxes during the building of the fiber cake. While that arrangement is in perfect balance when stationary, I have found that, when put in motion, detrimental stresses occur,

and at the moment of reversal of motion a TRAVERSE MECEANISE.

couple results which gives rise to a jarring action, which necessitates a severe limitation ofthe length and speed of operation of the machine. The present arrangement is such,

on the contrary, that these stresses are prac tlcally eliminated; To this end, the spin- 0 ning boxes are divided intogroups to which traverse motion in opposite directions is imparted'simultaneously with the result that not only are theweights balanced with respect to each other on opposite sides of the machine, but the strains on the traverse mechanism on eachside of the machine are lessened as Well as balanced, with the result that the length of the machine as a Whole may be greatly increased and the speed of traverse accelerated without detrimental effect or danger of harm to the apparatus.

. To illustrate theinvention, portion of one end of the frame 5 is shown, it being understood that the arrangement is the same on both sides of the frame. The spinning boxes 6, of which but one is shown, are supported on spindles 7 driven by electric motors 8 which rest on builder bars 9, 9, etc. The usual long builder bar is thus suitably subdivided, each subdivision carrying a group of motors 8 and their associated spindles and spinning boxes. In the form illustrated, six motors-and associated parts are carried on each division of the builder bar. The ends of each section of the builder bar are guided in slideways 10 supported by posts 11 resting on one of the main longitudinals 12 ofthe frame. Midway of its length, each builder bar 9,9, etc. is engaged by a lifting rod 13 passing through a guide s eeve 14 and provided at its lower end with a roller .15, which bears upon the inclined cam 16 of the "traverse bar 17. The latter extends the full length of the machine, and alternate lifting cams 16, 16 are reversely arranged so that upon .the horizontal reciprocation of the traverse bar 17 alternate spindle groups are oppositely reciprocated in a vertical direction. Thus, upon the move- .100 ment of the traverse bar 17 to the right, the builder bar 9 is lifted by the running up of the roller 15 on the cam 16,while the adjacent builder bar 9 is lowered by the running down of its roller on the oppositely of the weight of the down-coming builder 5 bars impart a thrust to the traverse bar,

through the cams, which aids the driving mechanism. a

Longitudinal reciprocating motion is imparted to the traverse bar by the spiral cam 18 on the shaft 19 of the worm gear 20 meshing with "the worm 21 at the lower end of the shaft 22. The upper end of the latter is also provided with a worm wheel 23, meshing with the worm 24' on the shaft 25 drlven by any suitable driver, e. g., a belt 26. The engagement between the traverse shaft 17 and the spiral cam 18 is attained by a roller 27 on the stud 28 passing through one end of the traverse bar and engaging in the peripheral raceway of the spiral cam 18. The stud is extended on the opposite side i also of the bar 17 and carries a slide block 30 (Fig. 2) working in the slideway 31 formed in the gear casing 32. v

boxes 6, it is desirable to raise the latter out of the chambers 33 in which they arevertically reciprocated by the traverse motion during the spinning operation, in order that the boxes may be readily removed from their spindles 7 for unloading the fiber cakes, To this end the traverse bar 17 is supported through rollers 34 at the upper ends of plungers 35 working in pressure cylinders 36. 35 Upon the admission of pneumatic or hydraulic pressure to the lower ends of the cylinders 36, the plungers are raised, thus lifting the traverse bar 17 vertically. Inasmuch as the builder bars are still supported by the latter, they are all simultaneously raised and the spinning boxes 6 lifted out of, or to a position in the upper portion of, the spinning chambers '33 at which they are accessible for ready removal. A link 37 interposed between the driving cam 18 and the traverse bar 17 permits the latter to be lifted without breaking connection with the cam;

in order to insure the upward movement of the builder bars in unison upon admission of pressure to the cylinders 36, I provide a equalizer shaft '38 carrying gears 39 Whit. mesh with racks a0 formedon the plungers 35. Obviously this rigid interconnection of the several plunger racks through the equal-- izer shaft 38 insures their simultaneous and equal rise. p

In Fig. 3 I have indicated a modified form of lifting cam on the traverse bar 17. The

inclined face of the cam, against which the roller 15 bears, is provided at its opposite ends with inclines 41 of lower pitch in order to facilitate the reversal of the traverse motlon at opposite ends of the longitudinal stroke of the traverse bar.

Various modifications of construction will After the fiber cakes have been spun in the.

{eadily occur to those dealing with the probdetails -illustrated.

I claim- .In a machine of the type described, a series of builder bars, spinning devices supported thereon, a horizontally reciprocating traverse bar common to said series of builder bars, and lifting cams fixed on said traverse bar, said cams being shaped to effect the simultaneous rise and fall of independent builder bars in opposite directions;
